These devices can load multiple "*.img" files. As with older devices, they must reside in a directory called "Garmin" on the SD-card (so the full path is "Garmin/*.img"). If the "Garmin" directory does not exist on the SD-card, one must be created.

Though there is no particular requirement to do so, when maps are distributed as multiple ".img" files, use the mkgmap command "mkgmap --gmapsupp mapA.img mapB.img mapC.img [...]" to combine them into a single file. This makes it easier to enable and disable the map in the on-device "Setup|Map|Map Information Select Map" menu.

As multiple ".img" files are permitted on the device, it is relatively simple to load more than one map set on the device. When loaded as individual files, each map may be individually enabled and disabled from the on-device "Setup|Map|Map Information Select Map" menu. It can be convenient to have the ability to enable and disable individual maps.

When multiple ".img" files are installed on the SD-card, it is difficult to differentiate them in the device menu when they all have the default "OSM Street Map" name set in the ".img" file header, but it is relatively simple to edit the on-device name. See the What if I have an existing gmapsupp.img file paragraph on the OSM Map On Garmin page for detailed information on how to do so.

Some of these maps are only distributed as executable installers for Windows. Run the installer under Wine to unpack the .img map files for other platforms.

Nearly all maps have integrated contourlines based on Viewfinderpanoramas or SRTM 1/3. North America maps, Mac OSx maps and full map of Europe available for people who donate to Velomap/Openmtbmap.

Road and Trekking bike focussed. Autorouting with preference for quiet streets, cycleways, cycleroutes and tertiarys outside cities. using amongst others class:bicycle for route calculation. No autorouting on motorways/trunk roads. Aims to display any bicycle related features and ways. 1 GPS Layout & 1 Desktop layout. Nearly all maps have integrated contourlines based on Viewfinderpanoramas or SRTM 1/3. North America maps, Mac OSx maps and full map of Europe available for people who donate to Velomap/Openmtbmap.

Maps created by mkgmap compiled together with 50 m interval SRTM terrain contours. Download available with the use of a BitTorrent client only. Azureus/Vuze plugin for automatic download/update of selected regions is available as well.

Covers generally one country per map, while BeNeLux and D/A/CH are one single map each. Routing enabled, address search works (house numbers/names by extra layer for D/A/CH). Additional layers offered respectively for contours, cycleways, marine mapping, hiking trails and public transport. Offers additionally a single street map of entire Europe plus extra layers.

Usually updated every 1-2 weeks. Routable version with or without contours available for Ireland, Great Britain and the British Isles (UK) (separate mapsets) complete with rendered sea. 'TT 1:50K Look n Feel' versions of the mapsets are also available. Other countries available on request! The maps now work directly in BaseCamp when the GPS is attached to the computer. User:Talkytoaster

Topographic maps for the general use in the spare time and for outdoor activities. Combined usage possible: with BaseCamp for route planing; as paper map after print out; with GPSr for outdoor navigation.

Radkarte. Map designed for the everyday cyclist.. Based on User:Radfahrer/Radkarte, changes in the map design. Focus on bicycle routes, bicycle auto-routing and topographic map display. Scripts available at launchpad.

Just unzip the gmapsupp.img file into the "Garmin" or "Map" folder of your device, see OSM_Map_On_Garmin/Mass_Storage_Mode . There are the maps from http://www.nzopengps.org included as separate layers (once copied on the device, deactivate the nzopengps.org layers to see the underlaying OSM layers)
